What are the RPC frameworks in PHP7.0?

With the continuous development of computer technology, distributed systems have become mainstream, and remote procedure call (RPC) is an important means to implement distributed systems. As a popular Web programming language, PHP also has its own RPC framework, among which some new RPC frameworks were introduced in PHP7.0 version. This article will introduce the common RPC frameworks and their characteristics in PHP7.0.

1. PHP Remote Procedure Call (phpRPC)

phpRPC is a lightweight RPC framework that is fast, easy to use, and scalable. phpRPC supports multiple protocols (such as TCP, UDP, HTTP, etc.) and uses XML document format for data interaction. phpRPC also supports custom transmission protocols to meet the needs of different scenarios. At the same time, phpRPC provides a rich exception handling mechanism to accurately track and handle errors, allowing developers to debug more efficiently.

2. Thruway

Thruway is an RPC framework for the WAMP protocol (WebSocket Application Message Protocol) implemented in PHP. The WAMP protocol is a two-way asynchronous messaging protocol based on WebSocket. . Thruway is characterized by its high scalability and high performance. It is implemented based on the ReactPHP framework, uses asynchronous I/O to handle massive network requests, and supports multi-process and multi-thread modes. Thruway also supports multiple authentication mechanisms, including anonymous authentication, key authentication and TLS/SSL encryption authentication.

3. gRPC

gRPC is a cross-language RPC framework that supports multiple languages ​​(such as C, Java, Python, etc.), and is also available in PHP7.0 expansion pack. gRPC provides protocol buffer (protobuf) as a data interaction format, making data transmission more efficient. gRPC also supports a variety of streaming data transmission mechanisms (including client-side streams, server-side streams, and bidirectional streams), which provides a lot of convenience for realizing real-time communication. In addition, gRPC also provides a variety of load balancing and failure recovery mechanisms, making the system more robust and reliable.

4. yar

yar is an RPC framework based on the HTTP protocol. It is written using PHP's native extension mechanism and is lightweight, high-performance and easy to learn. advantage. Yar uses JSON format for data interaction and supports custom data compression and serialization mechanisms. Yar also supports exception handling mechanism and debugging mode, and also provides a variety of security authentication mechanisms, including IP whitelist, HTTP authentication and digital signature authentication.

Summary

To sum up, there are many excellent RPC frameworks to choose from in PHP7.0. They each have their own characteristics and can be flexibly selected according to needs and scenarios. The four RPC frameworks introduced above all have high availability and stability, which can help developers implement remote procedure calls more conveniently and accelerate the deployment and development of distributed systems.
